Armstrong 182212-843 E14.2 Circulating Pump

Commercial radiant systems use Armstrong 182212-843 E14.2 to circulate up to 68 GPM against a maximum head of 32 feet. This 120 V single-phase dry-rotor circulator uses a cast iron body, stainless steel shaft, and silicon carbide mechanical seal for closed-loop hydronic heating. Purge trapped air, verify the in-line orientation, and check system pressure before energizing the pump.

The Armstrong E14.2 supports horizontal or vertical in-line installation and uses a stainless steel shaft with silicon carbide mechanical sealing. Its 120 V single-phase motor suits compatible commercial radiant systems, while the cast iron body supports closed-loop hydronic service. Verified data does not include amp draw, RPM, connection size, operating temperature, dimensions, weight, thermal protection, pressure-switch settings, or self-priming capability, so confirm the installation details and pump curve before ordering.
